37467-27-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 37467-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,4,6 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 37467-27:
(7*3)+(6*7)+(5*4)+(4*6)+(3*7)+(2*2)+(1*7)=139
139 % 10 = 9
So 37467-27-9 is a valid CAS Registry Number.

Δ2-1,2,4-oxadiazolines by condensation of amidoximes with ketones and aldehydes
Lessel
, p. 383 - 389 (1993)
Using acetic acid as a solvent, ketones and aromatic aldehydes react with amidoximes 1 to cyclic products, Δ2-1,2,4-oxadiazolines 3. The lack of reactivity in neutral milieu is explained by MNDO calculations. Protonated carbonyl compounds are discussed to be the reactive species.
